From 8e3c55386f6a3178d627311f734769bd4a881ff1 Mon Sep 17 00:00:00 2001 From: Gagandeep Singh Date: Wed, 17 Nov 2021 13:10:31 +0530 Subject: [PATCH] app/crypto-perf: increase segment size for IPsec Application calculates segment size based on buffer size plus digest size only, But if the operation mode is IPsec then packet length can be increased by some more bytes depending on the algorithm. In this patch, increasing segment size with RTE_PKTMBUF_HEADROOM when there is no user given segment size.
